ok so the rims or wheels will fit is that correct? also the ones I'm looking at are winter tires that the side Walls say 195/55 R16. I think the wheel are stock and that someone just threw winter tires on.
will that have an effect on the cars speed also?
sorry I should have been more clear in the beginning with my questions

In the first post you said they were 15" wheels. If they are 16" wheels (last digits on the tire specs), then that is an inch larger diameter than factory. I would not go that tall on a 2007 Fit.

You just have to watch the total diameter. Wheel diameter is only part of the equation.

Use that tire calculator above or try www.willtheyfit.com to see what sizes are close to stock.

Tire size work like this...first number is width in mm, second number is the percent of the width that is for the sidewall. Meaning that a 195/55 is 195mm wide and the sidewall is 195x.55 = 107.25mm tall sidewall.

For overall diameter, you have to include the sidewall twice. So, 107.25 x 2 = 214.5. Convert to inches - 8.44 inches

So, if you put that tire on a 15" wheel, you have a total diameter of 23.44. Put that spec tire on a 16" wheel and you have a 24.44 diameter.

My point is that, if you go up in diameter, you need to go to a tire with less sidewall (ie. 45 aspect ratio) in order to keep the overall diameter the same.

Short answer is that a 195/55-16 is too tall for your car. Also, it's better to go down in wheel diameter for snow tires instead of up. You want more sidewall for better impact resistance. Most run 14 or 15" wheels for winter use.
